I've opened a bounty of 50 reputation on one of my question: How could I create gaze buttons using React VR? but it didn't receive an answer that could help me from any other Stack Overflow user. After research and development I've found an answer and answered my own question.
The bounty on this question will be lost because I couldn't receive it to anyone else. So my question is now: if a bounty haven't receive the attention that was needed to solve it, could I receive it back?
